' VEHICLE-TIRE.

Specification of Letters Patent. Patented Apr. 11, 1911,

Application filed September 7, 1910. Serial No. 580,847.

To all whom itmay concern:

Be it known that I, ALBERT P. BUR'nUs, a

citizen of the United States-of America, re

siding at Prescott,.i n the county of Nevada and State of Arkansas, have invented new and useful Improvements in Vehicle-Tires,

of which the following is a specification.

This invention relates to vehicle tires and particularly to one designed for use in connection with the well known form of pneu-,

matic tire for automobiles, the object of the invention being to provide a novel form .of tire which is constructed for the interchangeable engagement with the wheels of the automobile and which is designed to permit the operator'of the vehicle to propel the samealong a railroad track structure.

In the drawing, forming aportion of this specification and in which like numerals of reference indicate similar parts in the several views :-Figure 1 is a. side elevation of my improved tire. Fig. 2 is a detail vertical section therethrough showing its application to the tire of an automobile wheel. Fig. 3 is a detail transverse section taken on the line The tire is constructed preferably of malleable iron or the like and formed to provide a continuous annular tread surface lwhich conforms in. configuration with the tread surface of the ball A of the rail B. This surface .1 has formed thereon at one side an annular guard flangel2 which extends clownwardly at one side of the rail as clearly shown in Fig. 2 of the drawing. The body I member 3 is formed to provide an annular tire-receiving concavity 4 to receive the tire 5 .of the wheel 6. The concavity is defined by the-inwardly extending guard flange 7 and a similar guard flange 8. From the flange 8 extend the spokes 9 whose inner ends are spaced from each other'to form an opening 10 for the reception of the hub 11 of the wheel. The spokes 9 at their inner ends are curved into the body member 3 so i as to be disposed immediately above the ball portion A of the rail-B.

In practice, the pneumatic tire of the vehicle wheel is deflated. My improved tire isthen placed over the said pneumatic tire and thetire inflated so as to cause the same to snugly fit the concavity 4. In placing my improved tire on the tire of the vehicle wheel it is desirable to arrange the spokes 9 diametrically opposite certain of the spokes of the vehicle wheel and to opera'tively conneet the spokes of the vehicle wheel with the spokes 9, I provide the U-shaped clamping clips or bolts 12 as particularly shown in Fig. 3 of the drawing.

From the construction of the tire described it will be seen that after one has,

been associated with the wheel of an automobile, the automobile will be adapted'to travel on the rails of a track structure.

I claim:

having pneumatic tires, comprising a member formedto provide. an annular concavity for the reception of the pneumatic tire and into which the tire when inflated will be expanded against the walls of such concavity, the said member having a tread flange surface thcreon and formed at one side..of the" said surface to provide an annular guard flange, spokes extending inwardly toward the hub of the wheel and formed to provide a hub-receiving passage, and fastening devices connecting the spokes of the member with thespokes of the wheel.

I A supplemental tire for vehicle wheels In testimony whereof I atfix my signature in presence of two witnesses.
